Holm AB, Helsingfors, Finland, a joint-stock company of Finland Filed Feb. 10, 1965, Ser. No. 431,645 Claims priority, application Finland, Feb. 14, 1964, 300/64 4 Claims. (Cl. 294-74) This invention relates to a band for lifting and/ or binding of diiferent kinds of objects for example when handling cargoes or other loads. The band consists of a number of threads which are interwoven, braided, glued or in some other way bound together. As used herein the word threads is deemed to include fibres as well as single or multiple threads of an organic, inorganic, or metallic material. The band is provided with at least one loop at one or both of its ends, in which case the threads at the loop part of the band are divided into at least two lines containing equal or different number of threads connected to form the stated loop.

It has been proposed in connection with ropes provided with fastening loops to form the loops by dividing the threads at the end of the rope into two groups, twisting the threads in each of groups to form a line and to twist both lines around one another in a screw-like manner to form a closed loop.

A disadvantage of loops formed in the above stated manner is that the ends of the threads do not keep their fixed position in the finished loop. In order to prevent the thread-ends from unwinding, with the risk of the whole loop loosening and breaking, it has been necessary in a suitable way to fasten the ends of the threads to the rope, generally by splicing or sewing, or by using special clasping rings, the making and fastening of which again demands extra work and expense.

It is an object of the invention to produce a band which avoids the above stated disadvantages of the previously proposed bands. According to the invention there is provided a band for lifting and/ or binding of objects, consisting of a number of connected threads and provided at least one end thereof with at least one loop, wherein said loop or each loop is formed by two loop-forming portions each consisting of a number of end portions of said threads braided to form an open mesh tube, and wherein at least one of the loop-forming portions is inserted axially into the other of the loop-forming portions in a manner such that it is wholly or partially enclosed therein and is firmly gripped thereby.

By producing a band in accordance with the invention it is possible, owing to the mutual frictional and applied force existing between the braided loop-forming portions, to avoid sewing or splicing of ends and the use of clasping rings or other external means for fastening the ends of the loop-forming portions.

In order that the invention may be clearly understood some embodiments thereof will now be described, by way of example, with reference to the accompanying drawing, in which FIGURE 1 is an embodiment of the invention showing a band with an open end,

FIGURE 2 shows a band in which the loop is finished,

FIGURE 3 schematically illustrates a band with a loop according to another embodiment, and

FIGURE 4 schematically illustrates a band having a modified loop.

Referring to the drawings, FIGURES 1 and 2 illustrate a flat band indicated generally by reference numeral 1 and which consists of a number of interwoven threads 2. At

the end of the band the threads are divided into two groups and braided together to form two open mesh tubular loopforming portions 3, 4. As shown in FIGURE 2, the loopforming portion 3 is inserted into the portion 4, so that the portion 4 surrounds the portion 3 along the entire length thereof. The portions 3, 4 are by this means formed into a closed loop, which is generally designated by numeral 5.

The loop-forming portions 3 and 4 are identical so that either one of the portions may be inserted into the other. The threads 2 in the loop-forming portions are braided With a pitch which allows axial compression of the loop-forming portions. When one loop-forming portion is axially compressed the threads are forced radially outwards so that the diameter of the loop-forming portion is increased. The outer loop-forming portion is not axially compressed and, being of lesser diameter, can easily be inserted axially into the axially compressed portion until it is wholly contained in the outer portion. When the axial compression is released the outer loop-forming portion tends to return to the original condition thereof and so firmly grips the inner loop-forming portion so that the co-operating loop-forming portions together form a closed loop.

There is in the above manner obtained a most reliable, firm mode of binding together the two loop-forming portions which is due not only to the considerable frictional effect between the two portions owing to the big contacting area, but also to the uneven, rough surfaces of the braided lines which grip one another and cause a mechanical binding effect between the two surfaces.

In FIGURE 3 there is illustrated an embodiment of the invention in which a number of threads 12 are braided to form a band 11. The end portions of the threads are, as in the previous embodiment, braided to form two loopforming portions 13 and 14, which are inserted one within the other to form a loop 15. In this embodiment the loop-forming portion 13 is inserted into the loopforming portion 14 at about the middle thereof so that the portion 14 surrounds only about one half of the portion 13 at the free end thereof. The loop-forming portion 14 is in a corresponding way inserted into the loop forming portion 13 at about the middle thereof so that the portion 13 surrounds the free end portion of the loop-forming portion 14.

The embodiment shown in FIGURE 4 differs from the one illustrated in FIGURE 3 therein that both of the free end portions 13' and 14' of the loop-forming portions 13 and 14 are least once threaded out of the loop.

The procedure of producing the band naturally depends on the kind of work it is to perform and its construction may thus vary from that described above, for example the band may be provided with several loops at the same end of the band, in which case the threads 2 of the band will be divided into suitable groups, which again are braided into loop-forming portions, which are paired for threading one into the other.

What I claim is:

1. A band for lifting and/ or binding of objects, consisting of a number of interconnected threads and provided at least one end thereof with at least one loop, wherein said loop or each loop is formed by two loopforming portions each consisting of a number of end portions of said threads braided to form an open mesh tube, and wherein at least one of the loop-forming portions is inserted axially into the other of the loop-forming portions in a manner such that it is wholly or partially enclosed therein and is firmly gripped thereby.

2. A band according to claim 1, wherein substantially the entire length of one loop-forming portion is inserted 3 4 into the other loop-forming portion and is gripped there- References Cited by the Examiner by. P
